    First set of Follow Up Labs since Starting TRT. Looking for Feedback

    Thanks for the feedback. I’m willing to try what the doc laid out for me. He feels the same way about my target E2 number. I don’t use HCG. I would say my natural production has completely shut down. I have been injecting for almost 3 months.

    First set of Follow Up Labs since Starting TRT. Looking for Feedback

    I took another Covid test and it came back positive. I knew it couldn’t be hormonal. Wish me luck that recovery is short. My symptoms are mild besides headaches and my blood pressure going up a little.

    Thanks. It may not be a bad idea to try that. My blood pressure has gone down a decent amount today. It averaged 127/79 this morning at about 930, did a good cardio workout and had a sauna at the gym. After that I took a few more readings and it averaged 133/77. Body still not feeling great and...

    First set of Follow Up Labs since Starting TRT. Looking for Feedback

    I had my follow up with Dr. Calkins on Wednesday afternoon. He did a really good job of listening to me and how I was feeling, not just my lab numbers. He did like how my labs looked overall. He actually said they were really good for being just over two months in. I agree with that sentiment as...

    First set of Follow Up Labs since Starting TRT. Looking for Feedback

    On Thursday around dinner, I decided to take a .125 anastrozole to see if it would relieve any of my fatigue, anxiety, and libido issues. I injected Friday like I normally do, and had a pretty good day. Both Thursday and Friday evening I did have some OK nocturnal erections and morning wood...

    First set of Follow Up Labs since Starting TRT. Looking for Feedback

    Thanks for the in-depth reply. There’s a lot to digest there. A couple things to give a little more context. My PA told me it didn’t matter when I pulled labs as long as I did it before my next injection. I asked him if he wanted me to wait until Monday to be at a 72 hour trough, and he said it...

    First set of Follow Up Labs since Starting TRT. Looking for Feedback

    I don’t cut the pills, that’s what empower compound them at. When I say my libido was good I mean my mental desire to want to have sex, physically there was nothing there. Struggled with ED and maintaining your erection without Cialis. I guess we all kind of define libido differently. My free T...

    First set of Follow Up Labs since Starting TRT. Looking for Feedback

    5 mg daily cialis. Started 6 grams of citrine a day this week. It’s libido as much as arousal. That’s the concerning part. Even before therapy, my libido was strong, arousal and erection quality was up and down.

    First set of Follow Up Labs since Starting TRT. Looking for Feedback

    Well, I can tell you I have no intentions on dropping my dosage down to 50 mg a week. The lowest I would even think about going right now would be 80, and I’m not even sure I’m going to do that. My biggest concern really is the sexual side effects. They are as bad if not a little worse than when...

    First set of Follow Up Labs since Starting TRT. Looking for Feedback

    First off, I want to thank everybody giving feedback on this thread. I appreciate it all of your views, and I agree with a lot of what all of you were saying. I know I’m definitely overmedicated on some level for me, but it might not be for other people. Having all the sexual side effects...

    First set of Follow Up Labs since Starting TRT. Looking for Feedback

    I am not taking any other meds except for 5 mg daily cialis in the mornings and a low dose atorvistatin. I know you are a big advocate of keeping estrogen higher, but it does not treat me well. I do appreciate your feedback and thoughts on what might be causing my issues.

    First set of Follow Up Labs since Starting TRT. Looking for Feedback

    I’ve been short tempered, been suffering from anxiety and have gotten lightheadedness off and on. I am also showing a lot of sleepiness around dinner time before I eat, especially on the days I inject. My libido has not been very good, and I am suffering from moderate erectile dysfunction and...

    First set of Follow Up Labs since Starting TRT. Looking for Feedback

    I did take .125 anastrazole a few times when symptoms got really bad. Every time it killed the anxiety and light headed feeling. Sometimes it fired up my libido, other times it did not. I had not taken any for almost two weeks before my labs. I inject sub q, most recently in my fat caps above my...

    First set of Follow Up Labs since Starting TRT. Looking for Feedback

    So I just got back my first follow up labs since starting TRT a little over two months ago. I was pretty pleased for the most part, as a lot of my numbers improved from a non-hormone standpoint. I was happy to see the drop in my hematocrit, and a lot of that has to do is me stopping iron...

    Starting TRT Soon

    Getting ready for my follow up labs very soon. Overall anxiety, exhaustion and muscle soreness became unbearable by the end of last week. It had never gotten that bad before I took a .125 AI pill on Saturday, and within two hours the anxiety and exhaustion went away. My libido and arousal were...

    Ice on sub q shot in belly

    After I injected this morning, I had a little sting at the shot location. I placed a cold gel pack on the shot location about 15 minutes after I injected. After I pulled it off, had a white film around the injection site that I had to scrape off my skin. Is it possible that the cold pack drew...

    Starting TRT Soon

    Thanks for the reply. I definitely agree that 100mg is not too low of a starting dose. I have two more weeks and get labs pulled, then I’ll know for sure.

    Starting TRT Soon

    Thank you. I am looking at the liquid melatonin @Nelson Vergel has discussed in other threads, and using 1 ml of it when I wake up. I pretty sure my mild prostate issues are trt related. I inject MWF, and today on Sunday morning, I woke up with zero irritation or inflammation. It’s been that way...

    Starting TRT Soon

    So I just finished week seven, and it’s been a more positive than negative right so far. The positives are I do have more overall energy. My weight is dropped from 210 to 198, I’ve put on some good muscle for seven weeks worth of workouts and I’ve lost a good bit of belly weight. The OK has...

    Starting TRT Soon

    As I continue to work my way through the first month, I am trying to troubleshoot side issues. My blood pressure calmed down and is consistently in a good range. My new issue is that the past four or five days, my prostate has begun to bother me. It is slightly inflamed and feels a little...

    Starting TRT Soon

    It’s now down to 131/71. RHR is 68-70 as well. Hoping it’s just my body going through another adjustment in the first few weeks.

    Starting TRT Soon

    How many of you had their blood pressure and heart rate increase randomly when starting trt. I’m on my 4th week and I’m getting increased blood pressure and resting heart rate issues the last two days. BP was 144/88 just a few minutes ago, and my resting heart rate in fluctuating between 78-88.

    I hear you. Thanks for the insight. I also have an increased pulse rate and headaches off and on. I assume this is normal as well.

    Starting TRT Soon

    Bump Took my third shot on Friday. After a quick libido boost, it went dead and has been the last couple of days yesterday and today I’m much more irritable and moody, energy is pretty decent. I know it’s early but I’m already wondering if 120 a week is too much of a starting test and I should...

    Starting TRT Soon

    Update: I am two shots into my protocol (40 ml Monday and Wednesday Morning), I decided to go down to 120mg to start vs. the 150 Defy suggested. My provider agreed that it was ok to start lower. I know it's beyond early, but I had a few things I wanted to run by you vets to get feedback on. The...

    Starting TRT Soon

    I also am thinking about pre-filling my syringes for the week on Sundays. Reasoning is I have two small children and mornings are quite hectic. I’d like to be able just to jump out of the shower, inject and move on with my morning. Anybody here have any experience pre-filling syringes, or...

    Meds and supplies finally came late yesterday. I’m going to start Monday to begin with a full 3x/week regiment. I let them know I am going to start at 120 a week, not 150.

    Starting TRT Soon

    He told me that he was requesting them in case I needed them, but he didn't feel like that I would. I was suprised it was that many tablets. I ordered a few to keep in case, but not that whole amount. He even said if I got to the point where E2 symptoms kicked in, to contact him and he would...

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
